Here's a random thought, let's just get rid of the word PAR and replace it with SSA. They both mean the same thing if you're comparing golf to disc golf, we could still keep birdies and bogeys as pop culture terms and no one would think "Oh, a Par 2, that would never happen on a golf course!"
We could just redo all tee signs over time to say "SSA X."
It's no less silly then worrying about what other people will think of us.
And probably about as productive in the long run.
And it sounds much cooler and more sophisticated. (I'll bet someone sees what I did there...)
